"He practices an awful lot and obviously the more you do that, the better you'll get. A few have flown in this season and I don't think that's down to luck. We all know the ability he's got. Hopefully he can keep that going for the rest of the season and score a few more."
Reds defender Nemanja Vidic added: "It was unbelievable. I think it was the best goal I've seen in a game I have played in."
Sir Alex Ferguson also gave Ronaldo's 13th-minute strike top billing, telling MUTV: "That must be the best free-kick in the Premier League.
"It was a marvellous hit. It was within two inches of the junction of the crossbar and the post. No goalkeeper in the world could possibly save it."
